Abstract

The incorporation of nanoparticles into hybrid carbon/glass composites significantly enhances their mechanical properties, making them suitable for various engineering applications. The primary aim of this study was to examine the effects of graphene nanoparticles (GNPs) on the mechanical and Charpy impact characteristics of carbon fiber/epoxy, glass fiber/epoxy, and their hybrid composite laminates across various laminate configurations. GNPs were uniformly dispersed in the epoxy matrix at different weight fractions of 0.1%, 0.25% and 0.5% (by weight). Experimental assessments encompassing flexural, tensile, and Charpy impact evaluations were carried out both with/without the incorporation of GNPs as reinforcing agents in the fabricated specimens. This research indicated that even a small addition of GNPs could lead to substantial improvements in tensile strength, flexural strength, and impact resistance due to better interfacial bonding between the fibers and the epoxy matrix. Upon introducing GNPs at a loading level of 0.1% (by weight), the experimental findings demonstrated a notable enhancement in the mechanical and impact properties of the hybrid composite laminates as a result of integrating GNPs into the epoxy matrix. This increase in strength can be attributed to the development of a strong interfacial bond among the fibers, epoxy, and GNPs leading to better load transferring from the matrix to the fibers.

石墨烯纳米片夹杂物对碳/玻璃复合材料力学性能的影响

将纳米颗粒掺入碳/玻璃复合材料中可以显著提高其机械性能，使其适用于各种工程应用。本研究的主要目的是研究石墨烯纳米颗粒（GNPs）对碳纤维/环氧树脂、玻璃纤维/环氧树脂及其混合复合材料层压板在不同层压结构下的力学和夏比冲击特性的影响。GNPs以0.1%、0.25%和0.5%（重量比）的质量分数均匀分散在环氧基体中。实验评估包括弯曲、拉伸和夏比冲击评估，在制造的样品中加入/不加入GNPs作为增强剂都进行了评估。这项研究表明，即使是少量的GNPs添加也可以显著提高纤维的抗拉强度、弯曲强度和抗冲击性，因为纤维和环氧基之间的界面结合更好。在0.1%（重量）的加载水平下，实验结果表明，由于将GNPs整合到环氧基体中，混杂复合材料层合板的机械性能和冲击性能显著增强。这种强度的增加可归因于纤维、环氧树脂和GNPs之间形成了强大的界面键，从而更好地将载荷从基体传递到纤维。图形抽象
